From Consultations to Courtrooms: Life as an ANP and Expert Witness
Healthcare professionals often wear many hats, but few roles are as varied and demanding as that of an Advanced Nurse Practitioner (ANP) working in general practice while also acting as an expert witness in clinical negligence cases.
In one part of my working life, I make timely clinical decisions for patients whose symptoms may be acute, complex or initially unclear. In the other, I examine past clinical decisions in detail, providing independent expert opinion in clinical negligence cases.
Moving between these two perspectives is demanding, but it also strengthens the judgement, objectivity and attention to detail that both roles require.
The Reality of a Busy General Practice
No two days in general practice are the same; a typical clinic may include a child with a fever, an adult with chest pain, a patient concerned about a new lump or skin lesion, someone experiencing a mental health crisis and an older person living with several complex conditions.
Every consultation begins with incomplete information. The challenge is therefore not simply to identify the most likely diagnosis, but also to recognise when a seemingly common presentation may indicate something more serious.
As an independent prescriber, I assess, diagnose, investigate, treat and prescribe for patients who often need a safe and appropriate plan within a single consultation. This involves identifying the most likely diagnosis, considering serious alternative diagnoses, deciding whether further investigation or referral is required, and clearly explaining what the patient should do if their symptoms change.
The challenge lies not only in recognising common conditions, but also in identifying the subtle signs that could indicate serious illness. Every consultation requires a balance of clinical knowledge, risk assessment, patient expectations and safe decision-making.
General practice is a demanding environment, with clinicians managing increasing levels of complexity alongside significant patient demand. Despite these pressures, patient safety remains the priority underpinning every clinical decision.
The Importance of Clinical Decision-Making
One of the most rewarding aspects of being an ANP is the opportunity to use advanced assessment and diagnostic skills to support patients at the point of need.
Whether managing a child with a suspected viral illness, assessing abdominal pain or determining whether a patient requires urgent referral, clinical reasoning plays a critical role. Decisions are rarely black and white. Instead, clinicians continually gather information, weigh up risks and make judgements based on the evidence available at that particular moment.
Documentation is equally important. Good clinical records are essential for continuity of care, but they also provide a record of the assessment undertaken, the clinical reasoning involved, the advice given and any safety-netting provided.
Transitioning from Clinician to Expert Witness
Alongside my clinical role, I work as an expert witness, preparing liability reports in clinical negligence cases. This involves reviewing medical records, witness statements, policies, guidelines and other relevant documentation to provide an independent opinion on whether the care provided was reasonable and consistent with the accepted standards of practice at the time.
Expert witness work requires a different mindset. Rather than making real-time decisions with limited information, I have the opportunity to review events retrospectively and consider the wider clinical picture.
The role demands objectivity, impartiality and a detailed understanding of professional standards. My duty is to the court rather than to either party involved in the case. The purpose is not to advocate for one side, but to assist the court by providing an independent professional opinion on complex clinical issues.
How General Practice Strengthens Expert Witness Work
One of the greatest advantages of combining these roles is that active clinical practice keeps my knowledge current and grounded in the realities of modern healthcare.
Working with acute and complex presentations on a daily basis provides an understanding of the pressures clinicians face, the limitations of the information available to them and the complexities involved in making decisions in a busy clinical environment.
When assessing a clinical negligence claim, it is important to consider what a reasonably competent practitioner would have done based on the information available at the time, not with the benefit of hindsight.
Remaining clinically active helps ensure that my expert opinions are informed by contemporary practice and the realities of frontline healthcare, rather than theoretical ideals alone.
How Expert Witness Work Improves Clinical Practice
The relationship works both ways.
Reviewing clinical negligence cases has heightened my awareness of risk management, documentation, communication and patient safety. Many cases highlight how important seemingly small aspects of clinical practice can be.
Issues may arise where key information was not documented, safety-netting advice was unclear, communication broke down, or important clinical information was not adequately shared between professionals and patients.
Examining these cases in detail reinforces the importance of thorough assessment, accurate record-keeping and clear communication during everyday consultations.
It also provides a valuable reminder that the quality of care is influenced not only by the clinical decision itself, but by how that decision is communicated, documented and followed through.
Maintaining the Balance
Balancing a busy general practice workload with medico-legal reporting requires organisation, discipline and a commitment to ongoing professional development.
Clinical work demands flexibility and responsiveness, while expert witness work requires focused periods of detailed analysis, research and report writing. Both roles involve significant responsibility and require a consistent commitment to professionalism and continuing development.
Despite the challenges, combining these roles is incredibly rewarding. It provides an opportunity to support patients directly while also contributing to the wider understanding of clinical practice, patient safety and professional accountability.
Final Thoughts
The role of the Advanced Nurse Practitioner continues to evolve, with ANPs playing an increasingly important part in delivering frontline healthcare.
Combining clinical practice with expert witness work provides a unique perspective on clinical decision-making, patient safety and professional accountability. The two roles may appear very different, but they share many of the same foundations.
Whether assessing and treating a patient presenting acutely in general practice or analysing a complex clinical negligence claim, the underlying principles remain the same: careful assessment, sound clinical judgement, evidence-based practice, clear communication and a commitment to high standards of care.
Ultimately, both roles are driven by a shared goal: supporting good clinical practice, promoting patient safety and contributing to better outcomes within healthcare.
